, combustion motors and aims to provide an improvedconstruction of this character in which a liquid fuel is sprayed under pres sure into the combustion chamber of the mo tor and a more or less continuous con'ibustion is maintained for actuating the motor un der the expansive action of the gas.

In carrying out the invention, I provide. a motor comprising a rotary combustion chamber associated with a rotary drive element mounted coaxiall'y with the combustion chamber and so arranged that the ex-- pansiveaction of the gas is exerted to impart opposite rotary movements to said combustion chamber and associated drive element.

' it is further sought to provide a multiple motor construction comprising units o'l the type described and cooperatively arranged to effect a continuous driving action to a common drive shaft.

'lVith these. and various otherminor objects in view, as will appear in the course of the following detailed specification, I will now describe the invention with reference to theiaccompanying drawings wherein one form or" construction is illustrated for embodying the proposed improvements, after which the particular novel features therein will he set forth and defined in the appended claims.

the sections of which the combustion chambers are i'ormed;

Fig. 7 is a detail sectional view taken on the 1ine T -7 of Fig. 3; and

Fig.8 is a detail sectional view taken on the line 88 of Fig. 2.

Referring now to the said drawings in detail, these illustrate the improved construction as com n'ising a pair of rotary combustion chambers 1O (Fig. 2) each made up of concave sections 12, 14-, approaching a semi-' spherical form, secured together by means of cap screws 16. The outer sections 12 are formed with hollow huh portions 18'journaled on trunnion blocks 20 mounted in the ends or" a bearing frame 22, while the inner sections Pl having bearing portions 24 supported on trunnions 26 which aremounted in a bushing 28 fitted in the transverse portion 30 of the bearing frame. 22. An asbestos screen 32 of spider form and having a central aperture 34, (as shown in Fig. 3), is clamped between each pair of sections. 12 and 14:.

Also mounted on-each of the trunnions '26 between each inner section 14 and, the

transverse portion 30 of the frame 2 2 is a .bevel gear wheel 36, one face. of which is .formed with a series of impact recessesor pockets 38 at the base of an annular channcl 40 located justinside the toothed periphery of each gearsvheel (see Figs. 5 and 7). 0n the other hand, each inner section 14 is formed with a pair of angularly extending lugs 42 adapted to freely travel in the chan nel 40 of the corresponding gear wheel 36, each lug being provided with a gas outlet passage 44 adapted to direct 'jets of gas frbm the corresponding combustionchamber '10 into the series of recesses or pockets 38. The structure of the said recesses or pockets 38 and the angular relation of the passages 44'.

are oppositely arranged in the two combustion chambers 10, since it is the purpose to drive the two units of the motor in opposite 4 directions as will be readily understood.

The bevel'gear wheels 36 each mesh with a bevel pinion i6 carried by a shaft 48 mounted in bearings 50 provided by the frame 22, and each or" the inner sections 14 of the combustion chambers is also formed with a bevel gear rim or flange 52 meshing on the opposite side'of the corresponding bevelpinion 46. Each bevel pinion 46 is formed with a plain pinion portion 54. and

these 'pinions. 54 are in mesh with opposite sides of a pinion 56 which is keyed to a main shaft 58 carried in a central bearing 60 in the-'frame 22, this shaft 58 being suitablyv equipped with a fan 62 and a. belt pulley ")4.

The'means for supplyin a suitable combustible mixture to the combustion chambers comprises,- in the illustrated construction,

an oil tank 66 which is connected by a pipe 10 appropriate pressure may be maintained by 68withan air pressure tank 70, in which an means of any suitable'type of pump 72 (see shanks projecting into the trunnion blocks 20 where the valve passages are brought into register with inwardly converging oil and air ducts 86 and 88. Each pair of these ducts discharge jointly into a flaring nozzle passage 90 which communicates through the axial passage 92 in the corresponding hub ortion 18 leading into one'of the com ustion chambers 10. A suitable spark plug 94 is carried by each of the hub portions 18 with its contacts positioned in the corresponding passage 92, each spark plu' having a rotary contact terminal 96 provi ed with an insulating collar 98 embracing the corre-' sponding hub portion 18. An insulated brush contact element 100 carried by the frame 22 engages each of the rotary terminals 96, said contacts 100 being made parts and type for interrupting the current through of an electric circuit which includes a battery 104 having at one side a conductor 106 (see Fig. 4) connected with the framework of the motor, and'at its other side having conductors 108 leadin to the spark plugs and rovided with suitable circuit making breaking devices 1110 of any desire the spark plugs. 4 Upper and lower pose of inclosing the motor parts from ,above and below.

In the operation of the above described construction, the oil is admitted from the tank 66 through the pi 78 and branch ipes 80 to the combustion chambers, and in view of the connections between said tank and the air tank it is apparent that the ressure therein is equalized, and the oil is; ed under this pressure into the nozzle pas-- sages 90, from which the oil is sprayed into correspondingly rotate the pinions housing sections 112 attached by screws 114 to opposite sides of the, bearing frame 22 are provided for the p,u1;-

the combustion chambers. The spark plugs 94 are provided for ignition purposes to start the combustion operation, and the presence of the screens 32 of asbestos material forms a fire cushion the action of which is to promote the combustion and sustain the same, keeping the combustion continuous and even entirely across the chambers 10. ,If deemed advisable, the interior faces of said chambers might be entirely lined with asbestos material for thus promoting the combustion of the fuel therein. The'arrangement of the lugs 42 providing the gas outlet passa es 44 is such asto form gas pressure ets w ereby the heated and expanding gas is directed in jets against the shoulders of the gas recesses or impact pockets 38 of the gear wheel 36, as indicated by the arrows 1n Figs. 3 and 7, and the impact of. these jets produces opposite rotary movements of each combustion chamber and its corresponding gear wheel 36, the channels 40 serving to confine the "as as much as possible until it has exerted substantially its full forceagainst the impact shoulders of said gas recesses or pockets. The effect of this rotation is to rotate the bevelpinions 46 inopposite directions and 54, whereby a continuous drive is transmitted to the intermediate pinion 56 and shaft 58, thus effecting rotation of the belt pulley 64 and the fan 62. The action of the fan 62 serves to expel the exhaust gas from around the motorparts and out through th opposite end of the housing, as indicated y the arrows in \Fig. 2, and thus tends to keep down parent that at any time one side of the motor the temperature of the motor. Of course if :may be at once cut oif and rendered inoperative, and thus only one side or unit of the imotor be continued in operation.

It will thus be apparent that I have de-- vised an efiicient and yet comparatively 'simplearrangement and construction for accomplishing the desired objects of the in vent on, and-while I have illustrated and de- I scribed one practical form of construction forfembodying thesame I desire to reserve I the right to make such formal-chain es or modifications as'may fairly fall within the scope of the appended claims.
